Description

本発明は自動車用座席などに用いられる発泡成形体(クッション部材)に被覆材(表皮材)を固定するための柔軟で長尺な係止部材、および、該係止部材を用いた被覆材固定方法に関する。   The present invention relates to a flexible and long locking member for fixing a covering material (skin material) to a foamed molded body (cushion member) used for an automobile seat and the like, and fixing of the covering material using the locking member Regarding the method.

発泡成形体の代表例の1つである自動車用座席(以下、シートということがある)用のクッション部材(シートクッション)に被覆材を取り付ける方法としては、クッション部材と被覆材の双方に埋め込まれた金属製ワイヤーを金属製リングで固定するホグリング工法、クッション部材と被覆材を接着剤で固定する接着工法、およびクッション部材に織編製またはプラスチック製のフック面ファスナーを埋め込み、被覆材の裏面に縫製されたループ面ファスナーをフック面ファスナーに係止固定する面ファスナーモールドイン工法がある。   As a method of attaching a covering material to a cushion member (seat cushion) for an automobile seat (hereinafter also referred to as a seat), which is one of the representative examples of the foamed molded article, it is embedded in both the cushion member and the covering material. Hog ring method for fixing a metal wire with a metal ring, an adhesive method for fixing a cushion member and a covering material with an adhesive, and embedding a woven or plastic hook hook-and-loop fastener in the cushion member, and sewing on the back surface of the covering material There is a hook-and-loop mold-in method for locking and fixing the loop hook-and-loop fastener to the hook hook-and-loop fastener.

近年、着座したときの身体のホールド性を向上させるためや座り心地を向上させるために、座面や背面が曲面形状である自動車用シートの使用が増加している。上記した被覆材固定方法の中で、面ファスナーモールドイン工法はシート製造工程の作業が容易である点およびシートのリサイクルのための分解作業が容易である点で優れるが、面ファスナーが長さ方向に変形しがたい構造であることから、シートの曲面形状への対応が困難であるという問題があった。   In recent years, in order to improve the holdability of the body when seated and to improve the sitting comfort, the use of an automobile seat having a curved surface on the seat surface and the back surface is increasing. Among the covering material fixing methods described above, the hook-and-loop fastener mold-in method is excellent in that the work of the sheet manufacturing process is easy and the disassembly work for recycling the sheet is easy. Therefore, there is a problem that it is difficult to cope with the curved surface shape of the sheet.

この問題を解決するために、シート曲面への対応を改善した面ファスナーモールドイン用の係合部材が提案されている。   In order to solve this problem, an engaging member for a hook-and-loop fastener mold-in that has improved the correspondence to the curved surface of the seat has been proposed.

例えば、帯状の係止部材の基部にほぼ箱状の膨張部を複数個形成し、該膨張部の表面に係合要素を立設して得られる帯状ファスナー部材が開示されている(特許文献1)。該箱状膨張部の変形性を利用することにより、帯状ファスナー部材が曲面に対応可能であると記載されている。しかし、複数個の膨張部を形成し、該膨張部表面に係合要素を立設するには複雑な製造工程が必要である。   For example, a belt-like fastener member obtained by forming a plurality of substantially box-like inflatable portions at the base of a belt-like locking member and standing an engaging element on the surface of the inflatable portion is disclosed (Patent Document 1). ). It is described that the belt-like fastener member can cope with a curved surface by utilizing the deformability of the box-shaped expansion portion. However, a complicated manufacturing process is required to form a plurality of inflatable portions and to erect engagement elements on the surface of the inflatable portions.

また、断面円形状の長尺可撓性体の周面上にフック係合素子群を形成したモールドイン成形用係止部材が開示される(特許文献2)。該モールドイン成形用係止部材は、通常クッション部材の表面に設けられた細い溝の底部に一体成形で装着される。被覆材の裏面に該係止部材の形状に対応したループ面ファスナーを装着し、該溝内にループ面ファスナー部を押入して両係合素子を係合させることにより被覆材がクッション部材に固定される。しかし、この方法では長尺可撓性体が必要であり安価に製造することができない。また、長尺可撓性体は違和感を生じ座り心地を悪くすることがある。   Moreover, a locking member for mold-in molding in which a hook engaging element group is formed on the peripheral surface of a long flexible body having a circular cross section is disclosed (Patent Document 2). The locking member for mold-in molding is usually attached to the bottom of a narrow groove provided on the surface of the cushion member by integral molding. A loop surface fastener corresponding to the shape of the locking member is attached to the back surface of the covering material, and the covering material is fixed to the cushion member by pushing the loop surface fastener portion into the groove and engaging both engaging elements. Is done. However, this method requires a long flexible body and cannot be manufactured at low cost. In addition, the long flexible body may cause an uncomfortable feeling and make it difficult to sit on.

被覆材に装着するループ面ファスナーに関してもいくつかの提案がなされている。例えば、帯状可撓性板の一方の面にループ係合素子を形成したループ面ファスナーが開示されている(特許文献3)。該ループ面ファスナーの長さ方向に沿う両端部を、重ね合わせた2枚の被覆材の端部にループ係合素子が外面になるように縫い付ける。次いで、外面に位置するループ係合素子をクッション部材の溝に押入することにより被覆材がクッション部材に固定される。しかし、この方法では帯状可撓性板が必要であり安価に製造することができない。また、帯状可撓性板は違和感を生じ座り心地を悪くすることがある。   Several proposals have also been made regarding loop hook-and-loop fasteners attached to a covering material. For example, a loop surface fastener in which a loop engaging element is formed on one surface of a belt-like flexible plate is disclosed (Patent Document 3). Both end portions along the length direction of the loop surface fastener are sewn to the end portions of the two overlapping covering materials so that the loop engaging element becomes the outer surface. Next, the covering material is fixed to the cushion member by pushing the loop engaging element located on the outer surface into the groove of the cushion member. However, this method requires a strip-like flexible plate and cannot be manufactured at low cost. In addition, the strip-shaped flexible plate may cause a sense of incongruity and make the sitting comfort worse.

また、表面の一部にループ係合素子を有する筒状面ファスナーの非係合素子部分にループ係合素子部分と略直角に外側に伸びる固着部を設け、該固着部に2枚の被覆材の端部を縫製などにより固着した後、該ループ係合素子部分をクッション部材の溝に押入することにより被覆材をクッション部材に固定する方法が開示されている(特許文献4)。しかし、この方法では筒状面ファスナーが潰れやすく、該溝への押入作業に時間、労力を有する。特許文献4には、筒状面ファスナー内部に柔軟な棒状芯体を挿入することが記載されている。しかし、クッション部材の溝が複雑な形状に形成されている場合、棒状芯体が挿入されたループ係合素子部分はこの複雑な形状の溝に容易に適合することができず、被覆材の装着作業に時間がかかる。   Also, a non-engaging element portion of the cylindrical surface fastener having a loop engaging element on a part of the surface is provided with a fixing portion extending outward substantially at right angles to the loop engaging element portion, and two covering materials are provided on the fixing portion. A method of fixing the covering material to the cushion member by pressing the loop engagement element portion into the groove of the cushion member after fixing the end of the cover by sewing or the like (Patent Document 4) is disclosed. However, in this method, the cylindrical surface fastener is easily crushed, and it takes time and labor to push into the groove. Patent Document 4 describes that a flexible rod-shaped core is inserted into a cylindrical surface fastener. However, when the groove of the cushion member is formed in a complicated shape, the loop engaging element part into which the rod-shaped core body is inserted cannot easily fit into the groove of the complicated shape, and the covering material is attached. It takes time to work.

上記のように、従来の被覆材固定用係止部材はクッション部材の溝内部への押入に手間がかかったり、二次元的、三次元的に複雑な形状に形成された溝に押入する作業が困難であった。また、複数の部材を用いるので、その製造コストも高かった。本発明は上記問題を解決し、クッション部材の溝への押入が容易であり、複雑な曲線形状の溝に容易に対応でき、かつ、その構造も簡単で安価に製造できる柔軟で長尺な被覆材固定用係止部材および作業能率が改善された被覆材固定方法を提供することを目的とする。   As described above, the conventional fixing member for fixing the covering material takes time to push the cushion member into the groove, or pushes into the groove formed in a complicated shape in two or three dimensions. It was difficult. In addition, since a plurality of members are used, the manufacturing cost is high. The present invention solves the above-mentioned problems, is easy to push into the groove of the cushion member, can easily cope with a complicated curved groove, and its structure is also simple and inexpensive and can be manufactured at a low cost. It is an object of the present invention to provide a material fixing locking member and a covering material fixing method with improved work efficiency.

本発明者等は、鋭意検討した結果、一方の表面にループ状係合素子を有するループ面ファスナーの他方の表面に、ループ面ファスナーの長さ方向に沿って樹脂層を形成することにより上記目的が達成されることを見出し、本発明を完成した。   As a result of intensive studies, the present inventors have formed a resin layer along the length direction of the loop surface fastener on the other surface of the loop surface fastener having a loop-shaped engagement element on one surface. Was achieved and the present invention was completed.

すなわち、本発明は、第1の主表面および該第1の主表面に対向する第2の主表面を有する帯状基布、該第2の主表面の少なくとも一部に該帯状基布の長さ方向に沿って立設されたループ係合素子、および、該第1の主表面上に形成された樹脂層A及び/又は樹脂層Bを有し、該樹脂層Aは該帯状基布の長さ方向に沿って中央部に不連続に形成され、該樹脂層Bは該帯状基布の長さ方向に沿って該帯状基布の両端部に連続または不連続に形成され、かつ、該樹脂層Aと該両端部の樹脂層Bとの間には樹脂層が形成されていない領域を有する被覆材固定用係止部材である。   That is, the present invention provides a belt-like base fabric having a first main surface and a second main surface opposite to the first main surface, and the length of the belt-like base fabric on at least a part of the second main surface. A loop engaging element erected along the direction, and a resin layer A and / or a resin layer B formed on the first main surface, the resin layer A being a length of the belt-like base fabric The resin layer B is formed discontinuously at the central portion along the length direction, and the resin layer B is formed continuously or discontinuously at both ends of the belt-shaped base fabric along the length direction of the belt-shaped base fabric, and the resin The covering member fixing locking member has a region where the resin layer is not formed between the layer A and the resin layer B at both ends.

さらに、本発明は、前記被覆材固定用係止部材の両端部を前記第1の主表面が内側になるように上方向に立ち上げ、該両端部を対向させて被覆材連結部を形成し、該係止部材を該被覆材連結部を介して被覆材に取り付け;該被覆材に取り付けた係止部材をクッション部材に形成された溝部に押入し、該係止部材のループ係合素子と該溝部底部に立設されたフック係合素子とを係合させ、よって、被覆材をクッション部材に固定させる工程を含む被覆材の固定方法である。   Further, according to the present invention, both end portions of the covering member fixing locking member are raised upward so that the first main surface is inside, and the both end portions are opposed to form a covering member connecting portion. The locking member is attached to the covering material via the covering material connecting portion; the locking member attached to the covering material is pushed into a groove formed in the cushion member, and the loop engaging element of the locking member is The covering member fixing method includes a step of engaging a hook engaging element erected on the bottom of the groove, thereby fixing the covering member to the cushion member.

本発明の被覆材固定用係止部材は、クッション部材の溝への押入が容易であり、複雑な曲線形状の溝に容易に対応できる。また、その構造も簡単で安価、容易に製造できる。従って、自動車用座席などの生産効率を大きく改善することができる。   The covering member fixing locking member of the present invention can be easily pushed into the groove of the cushion member, and can easily cope with a complicated curved groove. In addition, its structure is simple, inexpensive and can be easily manufactured. Therefore, the production efficiency of automobile seats can be greatly improved.

本発明で使用するループ面ファスナーは、編布製のループ面ファスナーであり、伸縮性が優れる点から、基布とループ係合素子がラッセル編みにより形成されたループ面ファスナーが好ましい。経糸、緯糸およびループ糸を織成して得られる織布製のループ面ファスナーは、基布の地組織が強固であるので柔軟性が低く、複雑な曲線状および曲面状の溝に適合するのに限界がある。ラッセル編みループ面ファスナーの基布は、変形しやすい糸及び編構成であり、かつ地組織が疎な構造で編糸間の隙間が大きいので変形が容易である。   The loop surface fastener used in the present invention is a loop surface fastener made of knitted fabric, and a loop surface fastener in which a base fabric and a loop engaging element are formed by Russell knitting is preferable from the viewpoint of excellent stretchability. Loop hook-and-loop fasteners made of woven fabric obtained by weaving warp, weft, and loop yarns are low in flexibility due to the strong base fabric structure, and are limited to fit into complex curved and curved grooves There is. The base fabric of the Russell knitted loop surface fastener has a yarn and knitting structure that are easily deformed, and has a structure with a sparse texture and a large gap between the knitting yarns, so that deformation is easy.

ループ面ファスナーに用いる繊維は、通常の布帛に使用される繊維であればよく、ポリアミド系繊維、ポリエステル系繊維、ポリオレフィン系繊維などが使用される。また、マルチフィラメントが好ましく、マルチフィラメントにモノフィラメントを混合してもよい。ループを構成するマルチフィラメントは、好ましくは5〜50本、より好ましくは10〜40本、さらに好ましくは15〜35本のフィラメントが無撚のストレートの状態で引き揃えられてマルチフィラメントを形成している、いわゆる生糸が好ましい。マルチフィラメントの太さとしては100〜250dtexが好ましい。一方、ループ面ファスナーの生地を構成するマルチフィラメント糸としては、200〜400dtexでフィラメント数が50〜150本の仮撚加工糸またはその合撚糸が好ましい。   The fiber used for the loop surface fastener may be a fiber used for a normal fabric, and polyamide fiber, polyester fiber, polyolefin fiber, or the like is used. Moreover, a multifilament is preferable and a monofilament may be mixed with the multifilament. The multifilament constituting the loop is preferably formed by aligning 5 to 50 filaments, more preferably 10 to 40 filaments, more preferably 15 to 35 filaments in a non-twisted straight state. So-called raw silk is preferred. The thickness of the multifilament is preferably 100 to 250 dtex. On the other hand, as the multifilament yarn constituting the loop surface fastener fabric, false twisted yarn having 200 to 400 dtex and 50 to 150 filaments or a twisted yarn thereof is preferable.

ループ面ファスナーは、公知の編布製造装置を用いて、公知の方法により製造される。ループ面ファスナーは基布と一方の表面に形成されたループ係合素子からなる。ループ面ファスナーの幅(基布の幅)は、クッション部材の大きさ、溝の幅と深さに応じて適宜選択されるが、通常10〜80mmである。ループ係合素子の高さおよび立設密度は、必要とされるフック係合素子との係合力に応じて決められるが、高さは1〜5mm、立設密度は(マルチフィラメントの場合には、マルチフィラメントからなるループを1個とカウント)20〜80個/cm2であるのが好ましい。ループ係合素子は基布の一方の表面全体に形成されていてもよい。しかし、後述するように、一方の表面全体に存在するループ係合素子の全てがクッション部材の溝部底面に設けられたフック係合素子との係合に関与するわけではないので、基布の長さ方向に沿う中央部のみに、クッション部材の溝部底面に設けられたフック係合素子に効果的に係合するように形成するのが好ましい。 The loop surface fastener is manufactured by a known method using a known knitted fabric manufacturing apparatus. The loop surface fastener includes a base fabric and a loop engaging element formed on one surface. The width of the loop surface fastener (the width of the base fabric) is appropriately selected according to the size of the cushion member and the width and depth of the groove, but is usually 10 to 80 mm. The height and standing density of the loop engaging element are determined according to the required engaging force with the hook engaging element, but the height is 1 to 5 mm, and the standing density (in the case of multifilament) The number of loops made of multifilament is counted as one), and is preferably 20 to 80 pieces / cm 2 . The loop engaging element may be formed on one entire surface of the base fabric. However, as will be described later, since not all of the loop engaging elements existing on one surface are involved in the engagement with the hook engaging elements provided on the groove bottom surface of the cushion member, the length of the base fabric It is preferable to form so as to be effectively engaged with the hook engaging element provided on the bottom surface of the groove portion of the cushion member only in the central portion along the vertical direction.

ループ面ファスナー(一方の表面にループ係合素子が形成された基布)の伸縮性は伸縮率及び伸縮弾性率で評価した。伸縮率は縦方向(長さ方向)で3%以上が好ましく、より好ましくは4〜15%、伸縮弾性率は45%以上が好ましい。   The stretchability of the loop surface fastener (the base fabric having a loop engaging element formed on one surface) was evaluated by the stretch rate and the stretch elastic modulus. The stretch rate is preferably 3% or more in the longitudinal direction (length direction), more preferably 4 to 15%, and the stretch elastic modulus is preferably 45% or more.

面ファスナーの伸縮率及び伸縮弾性率は次のようにして求めた。垂直に保持したTcm幅ループ面ファスナーの自由端に、T×2.5gの初期荷重(2.5g/cm)を掛け、30秒後の長さ(元長さ(a))を測定した。次に、T×250g(250g/cm)の荷重をかけ、30秒後の長さ(荷重時長さ(b))を測定した。荷重除去し、2分間放置した後に、再び初期荷重を掛け、30秒後の長さ(荷重履歴後長さ(c))を測定した。伸縮率は荷重時変形量を元長さで除した値、すなわち[100×(b−a)/a]であり、伸縮弾性率は回復量を荷重時変形量で除した値、すなわち[100×(b−c)/(b−a)]である。   The stretch rate and stretch elastic modulus of the surface fastener were determined as follows. An initial load (2.5 g / cm) of T × 2.5 g was applied to the free end of the Tcm-width loop surface fastener held vertically, and the length after 30 seconds (original length (a)) was measured. Next, a load of T × 250 g (250 g / cm) was applied, and the length after 30 seconds (length under load (b)) was measured. After removing the load and leaving it to stand for 2 minutes, an initial load was applied again, and the length after 30 seconds (the length after the load history (c)) was measured. The expansion / contraction rate is a value obtained by dividing the deformation amount under load by the original length, that is, [100 × (ba) / a], and the elastic modulus is a value obtained by dividing the recovery amount by the deformation amount during load, that is, [100 × (b−c) / (b−a)].

本発明では、基布とループ係合素子がラッセル編みにより形成されたループ面ファスナーを用いることが好ましい。ラッセル編みループ面ファスナーは公知のラッセル編み装置を用いて公知の方法により製造される。   In the present invention, it is preferable to use a loop surface fastener in which the base fabric and the loop engagement element are formed by Russell knitting. The raschel knitted loop surface fastener is manufactured by a known method using a known raschel knitting apparatus.

ループ面ファスナーのループ係合素子を有する面(第2の主表面)に対向する面(第1の主表面)には樹脂層が設けられる。樹脂層は、ループ面ファスナーの長さ方向に沿って、中央部及び/又は両端部に形成される。中央部に形成する樹脂層(樹脂層A)は長さ方向に不連続である。両端部に形成する樹脂層(樹脂層B)は長さ方向に連続でも不連続でもよいが連続であるのが好ましい。   A resin layer is provided on a surface (first main surface) facing the surface (second main surface) having the loop engaging element of the loop surface fastener. A resin layer is formed in a center part and / or both ends along the length direction of a loop surface fastener. The resin layer (resin layer A) formed in the center is discontinuous in the length direction. The resin layers (resin layer B) formed on both ends may be continuous or discontinuous in the length direction, but are preferably continuous.

樹脂層Aはループ係合素子を裏面から補強する効果を有する。樹脂層Aにより補強されていると、ループ係合素子を、クッション部材の溝部底面に設けられたフック係合素子に押圧し易く、より強固な係合を得ることができるので好ましい。クッション部材の溝部が二次元的、三次元的に複雑な形状を形成している場合、係止部材、特に係止部材のループ係合素子形成部分は、溝部開口部の形状に応じて自由に変形することが必要である。そのために、樹脂層Aは長さ方向に不連続に形成する。不連続にすると、樹脂層Aを形成した部分(裏面にループ係合素子を有する)の変形が容易になり、複雑な形状の溝部に係止部材を押入する操作が容易になる。   The resin layer A has an effect of reinforcing the loop engaging element from the back surface. Reinforcement by the resin layer A is preferable because the loop engagement element can be easily pressed against the hook engagement element provided on the bottom surface of the groove of the cushion member, and a stronger engagement can be obtained. When the groove of the cushion member has a complicated shape in two or three dimensions, the locking member, especially the loop engaging element forming portion of the locking member, can be freely selected according to the shape of the groove opening. It is necessary to deform. Therefore, the resin layer A is formed discontinuously in the length direction. When discontinuous, the portion where the resin layer A is formed (having the loop engaging element on the back surface) is easily deformed, and the operation of pushing the locking member into the complicatedly shaped groove portion is facilitated.

2つの樹脂層Bは係止部材の使用に際して被覆材に取り付けるための被覆材連結を形成する。また、係止部材をクッション部材の溝部に押入する際に、溝部の形状に応じて係止部材を直線状または湾曲状に保持する効果を有する。これにより、被覆材の固定作業が環便になり、また、溝部に沿って被覆材を精確に固定することができる。   The two resin layers B form a covering material connection for attaching to the covering material when the locking member is used. Further, when the locking member is pushed into the groove portion of the cushion member, there is an effect of holding the locking member linearly or curvedly according to the shape of the groove portion. Thereby, the fixing operation of the covering material becomes a convenience, and the covering material can be accurately fixed along the groove portion.

樹脂層AとBを形成するための樹脂は柔軟であり、ループ面ファスナーを形成する繊維と親和性があることが好ましくい。ポリエステル繊維やポリアミド繊維に対しては合成ゴム、ポリウレタン、軟質ポリエステル、軟質ポリアミド、軟質ポリオレフィン樹脂、アクリル樹脂などが使用できる。   The resin for forming the resin layers A and B is preferably flexible and has an affinity for the fibers forming the loop surface fastener. Synthetic rubber, polyurethane, soft polyester, soft polyamide, soft polyolefin resin, acrylic resin, etc. can be used for polyester fiber and polyamide fiber.

樹脂層AとBは、例えば、塗布法(ホットメルト法、スキージング法など)、接着法、融着法などの公知の方法により、前記樹脂をループ面ファスナーの基布に一部進入する状態で50〜300g/m2塗布することにより形成される。樹脂層AとBの幅は、係止部材の幅によって適宜決められるが、それぞれ3〜30mmが好ましい。厚さは、好ましくは0.1〜4mmである。樹脂層Aの幅と厚さは樹脂層Bのそれらと同一でも異なっていてもよく、2つの樹脂層Bの幅と厚さも同一でも異なっていてもよい。また、樹脂層AとBは係止部材の幅方向に不連続であっても連続であってもよい。 The resin layers A and B are, for example, a state in which the resin partially enters the base fabric of the loop surface fastener by a known method such as a coating method (hot melt method, squeezing method, etc.), an adhesion method, or a fusion method. It is formed by applying 50 to 300 g / m 2 . The widths of the resin layers A and B are appropriately determined depending on the width of the locking member, but are preferably 3 to 30 mm. The thickness is preferably 0.1 to 4 mm. The width and thickness of the resin layer A may be the same as or different from those of the resin layer B, and the width and thickness of the two resin layers B may be the same or different. Resin layers A and B may be discontinuous or continuous in the width direction of the locking member.

長尺のループ面ファスナーは、被覆材の固定作業を容易かつ精確に行うのに十分である程度の変形性を有することが好ましい。そのためには、ループ面ファスナーの基布の柔軟性と共に樹脂層AとBの柔軟性も適度であることが好ましい。樹脂層が形成されていない部分の基布の撓み抵抗力は、20g以下であるのが好ましく、10〜20gであるのがより好ましく、15〜18gであるのがさらに好ましい。また、樹脂層AまたはBを形成した部分の撓み抵抗力は25g以上であるのが好ましく、25〜80gであるのがより好ましく、30〜60gであるのがさらに好ましい。上記数値はいずれも帯状基布の幅方向の値である。上記範囲内であると、係止部材が柔らかすぎることがなく取り扱いが容易であり、また、変形性が適度であり、被覆材に装着した係止部材を溝に沿って変形させることが容易である。   It is preferable that the long loop surface fastener has a certain degree of deformability sufficient to easily and accurately fix the covering material. For that purpose, it is preferable that the flexibility of the resin layers A and B as well as the flexibility of the base fabric of the loop surface fastener is appropriate. The bending resistance of the base fabric in the portion where the resin layer is not formed is preferably 20 g or less, more preferably 10 to 20 g, and further preferably 15 to 18 g. Moreover, it is preferable that the deflection resistance of the part which formed the resin layer A or B is 25 g or more, It is more preferable that it is 25-80 g, It is further more preferable that it is 30-60 g. All of the above numerical values are values in the width direction of the belt-like base fabric. Within the above range, the locking member is not too soft and easy to handle, and the deformability is moderate, and it is easy to deform the locking member attached to the covering material along the groove. is there.

撓み抵抗力は、(株)大栄科学精器製作所製の撓み抵抗試験機“HOM−200”を用いて以下のようにして測定した。幅40mm、長さ200mmの樹脂層を形成した試料または形成していない試料(基布)を、撓み抵抗試験機のスリット(幅20mm)に長さ方向が直角になるように試料を戴置した。次いで、幅2mmの押圧板で下方向に試料に荷重をかけた。試料が、スリット面から下方向に10mm変形したときの荷重を測定し、撓み抵抗力とした。測定は第1の表面側から押圧した。   The bending resistance was measured as follows using a bending resistance tester “HOM-200” manufactured by Daiei Kagaku Seisakusho Co., Ltd. A sample in which a resin layer having a width of 40 mm and a length of 200 mm was formed or a sample (base fabric) not formed was placed on a slit (width 20 mm) of a bending resistance tester so that the length direction was perpendicular to the slit. . Next, a load was applied to the sample in the downward direction with a pressure plate having a width of 2 mm. The load when the sample was deformed 10 mm downward from the slit surface was measured and defined as the bending resistance. The measurement was pressed from the first surface side.

以下図面を参照して本発明を説明する。図1は本発明の係止部材1の一例を示す斜視概略図である。図2は図1の線V−Vに関する断面図である。   The present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view showing an example of the locking member 1 of the present invention. FIG. 2 is a cross-sectional view taken along line VV in FIG.

図1及び2において、基布2の第2の主表面中央部には係止部材1の長さ方向に沿ってループ係合素子3が立設されている。基布2の第1の主表面中央部には樹脂層4(樹脂層A)が係止部材1の長さ方向に不連続に形成されている。樹脂層4の連続部および不連続部の長さ、形状は必要とする変形容易性に応じて適宜決められる。樹脂層4はループ係合素子3をその反対面から補強するように形成するが、樹脂層Aとループ係合素子3の幅は同一でも異なっていてもよい。   1 and 2, a loop engagement element 3 is erected along the length direction of the locking member 1 at the center portion of the second main surface of the base fabric 2. A resin layer 4 (resin layer A) is formed discontinuously in the length direction of the locking member 1 at the center portion of the first main surface of the base fabric 2. The length and shape of the continuous part and the discontinuous part of the resin layer 4 are appropriately determined according to the required ease of deformation. The resin layer 4 is formed so as to reinforce the loop engaging element 3 from the opposite surface, but the width of the resin layer A and the loop engaging element 3 may be the same or different.

係止部材1の長さ方向に沿う両端部には樹脂層5,6(樹脂層B)が形成されている。必要に応じて、樹脂層5,6の幅方向外側に樹脂層が形成されていない耳部を設けてもよい。樹脂層4と樹脂層5,6の間には樹脂層が形成されていない領域が存在する。該領域の幅は2〜10mmであるのが好ましい。該領域が存在することにより、使用に際して、係止部材の両端部を上方に立ち上げ被覆材連結を形成する操作が容易になる。また、係止部材に適度な柔軟性および変形性を付与する。   Resin layers 5 and 6 (resin layer B) are formed at both ends along the length direction of the locking member 1. You may provide the ear | edge part in which the resin layer is not formed in the width direction outer side of the resin layers 5 and 6 as needed. A region where no resin layer is formed exists between the resin layer 4 and the resin layers 5 and 6. The width of the region is preferably 2 to 10 mm. The presence of the region facilitates the operation of raising both end portions of the locking member upward and forming the covering material connection in use. Moreover, moderate softness | flexibility and a deformability are provided to a locking member.

本発明においては、樹脂層4のみを形成してもよいし(図3)、樹脂層5,6のみを形成してもよい(図4)。   In the present invention, only the resin layer 4 may be formed (FIG. 3), or only the resin layers 5 and 6 may be formed (FIG. 4).

図5と6は、本発明の係止部材の使用態様例を示す図である。例えば、図1に示した係止部材を使用する場合、両端の樹脂層5と6を第1の主表面が内側になるように上方に立ち上げ、樹脂層5と樹脂層6を対向させて被覆材連結部を形成する。図5に示すように、樹脂層5と樹脂層6の間隙に2枚の被覆材(図示せず)の端部を挿入し縫製、接着剤などにより被覆材と樹脂層5,6を固着させ、係止部材を被覆材に取り付ける。また、図6に示すように、樹脂層5と樹脂層6を対向、密着させ、2つの樹脂層の外側に2枚の被覆材をそれぞれ固着させ、係止部材を被覆材に取り付けることもできる。図6の被覆材連結部に樹脂を付与して樹脂層5と樹脂層6を一体化してもよい。図5,6において、樹脂層4はほぼ平坦であるが、クッション部材の溝部底部に形成されるフック面ファスナーの形状に応じて、わずかに凹または凸状に湾曲してもよい。また、図5,6に示すように、樹脂層4から立ち上がる側部は、平滑でループ係合素子が存在しないことが好ましい。ループ係合素子が存在すると、狭い溝部へ係止部材を押入する際に、抵抗となり作業効率が低下し、また、ループ係合素子3とクッション部材の溝部底部のフック係合素子との係合位置が不正確になることもある。   5 and 6 are diagrams showing examples of how the locking member of the present invention is used. For example, when the locking member shown in FIG. 1 is used, the resin layers 5 and 6 at both ends are raised upward so that the first main surface is inside, and the resin layer 5 and the resin layer 6 are opposed to each other. A covering material connecting portion is formed. As shown in FIG. 5, the ends of two coating materials (not shown) are inserted into the gap between the resin layer 5 and the resin layer 6, and the coating material and the resin layers 5 and 6 are fixed by sewing, an adhesive, or the like. The locking member is attached to the covering material. In addition, as shown in FIG. 6, the resin layer 5 and the resin layer 6 are opposed to each other, closely attached to each other, and two covering materials are fixed to the outside of the two resin layers, and the locking member can be attached to the covering material. . The resin layer 5 and the resin layer 6 may be integrated by applying a resin to the covering material connecting portion in FIG. 5 and 6, the resin layer 4 is substantially flat, but may be slightly concave or convex depending on the shape of the hook hook-and-loop fastener formed at the groove bottom of the cushion member. As shown in FIGS. 5 and 6, it is preferable that the side portion rising from the resin layer 4 is smooth and has no loop engaging element. When the loop engaging element is present, when the locking member is pushed into the narrow groove portion, resistance is generated and work efficiency is lowered, and the loop engaging element 3 is engaged with the hook engaging element at the bottom of the groove portion of the cushion member. The position may be inaccurate.

図7は本発明の係止部材を取り付けた被覆材をクッション部材の溝部に固定する方法の一例を示す概略図である。クッション部材11の溝部底部にはフック係合素子12が立設されている。本発明の係止部材を取り付けた被覆材13を該溝部に押入し、ループ係合素子3をフック係合素子12に押圧、係合させることにより被覆材13がクッション部材11に固定される。被覆材としては、編織物、天然繊維または合成繊維の不織布、発泡ポリエチレン、発泡ポリスチレン、発泡ポリウレタンなどの発泡合成樹脂シート、天然または人工皮革シート、それらの積層体などが用いられる。クッション部材としては、発泡ウレタン、合成繊維積層体、天然繊維フェルトなどが用いられる。   FIG. 7 is a schematic view showing an example of a method of fixing the covering material to which the locking member of the present invention is attached to the groove portion of the cushion member. A hook engaging element 12 is erected on the bottom of the groove of the cushion member 11. The covering material 13 to which the locking member of the present invention is attached is pushed into the groove, and the covering material 13 is fixed to the cushion member 11 by pressing and engaging the loop engaging element 3 with the hook engaging element 12. Examples of the covering material include knitted fabrics, nonwoven fabrics of natural fibers or synthetic fibers, foamed synthetic resin sheets such as foamed polyethylene, foamed polystyrene, and foamed polyurethane, natural or artificial leather sheets, and laminates thereof. As the cushion member, foamed urethane, synthetic fiber laminate, natural fiber felt or the like is used.

以上のように、本発明の係止部材は樹脂層A及び/又は樹脂層Bを有し、長さ方向に二次元および三次元的な変形が容易であるのみならず、クッション部材への押入が容易となる適度な硬さを有する。被覆材の取り付けられた係止部材は任意の形状に作られた溝へ、その形状に応じた形状に変形して挿入し、クッション部材に強固に固定することができる。   As described above, the locking member of the present invention has the resin layer A and / or the resin layer B and is not only easily deformed two-dimensionally and three-dimensionally in the length direction but also pushed into the cushion member. It has a suitable hardness that makes it easy. The locking member to which the covering material is attached can be inserted into a groove formed in an arbitrary shape after being deformed into a shape corresponding to the shape, and can be firmly fixed to the cushion member.

該帯状ループ面ファスナーのループ係合素子形成面(第2の主表面)に対向する面(第1の主表面)の中央部に長手方向に沿ってポリアミド系樹脂(“マイクロメルト6211”
(株)ヘンケル社製)を用いて不連続樹脂層Aを形成した(幅10mm、厚さ120μm、10mm/5mmピッチ(塗工部/非塗工部))。さらに、前記ポリアミド系樹脂を用いて該帯状ループ面ファスナーの両端部に連続樹脂層Bを形成し(幅10mm、厚さ150μm)、図1と同様の構成の係止部材を製造した。得られた係止部材の樹脂層形成部分の撓み抵抗力は60g、非形成部分の撓み抵抗力は18gであった。
A polyamide-based resin (“micromelt 6211”) along the longitudinal direction at the center of the surface (first main surface) facing the loop engaging element forming surface (second main surface) of the belt-shaped loop surface fastener.
The discontinuous resin layer A was formed using (Henkel Co., Ltd.) (width 10 mm, thickness 120 μm, 10 mm / 5 mm pitch (coating part / non-coating part)). Furthermore, the continuous resin layer B was formed in the both ends of this strip | belt-shaped loop surface fastener using the said polyamide-type resin (width 10mm, thickness 150micrometer), and the locking member of the structure similar to FIG. 1 was manufactured. The bending resistance of the resin layer forming portion of the obtained locking member was 60 g, and the bending resistance of the non-formed portion was 18 g.

該係止部材の両端部の樹脂層Bを第1の主表面が内側になるように上に立ち上げ、図5に示すように対向させて被覆材連結部を形成した。該被覆材連結部に2枚の被覆材(ポリエステル繊維製の丸編地(株)クラレ)の端部を挿入し、縫製して係止部材を被覆材に取り付けた。次いで、曲線状の溝部を有し、該溝部の底部にフック係合素子が立設されている発泡ウレタン製クッション部材に前記被覆材を固定し自動車用シートを作製した。係止部材は曲線形状に従って容易に変形し、また、溝部内部への押入も抵抗なく行うことができ、係止部材のループ係合素子と溝部底部のフック係合素子を強固に係合させることができた。得られた自動車用シートに着座したところ座り心地がよく、また、長時間着座しても被覆材は弛んだりずれたりすることはなかった。 The resin layer B at both ends of the locking member was raised up so that the first main surface was inside, and opposed to each other as shown in FIG.

比較例1
第1の主表面前面に合成ゴム係樹脂を塗工した以外は実施例1と同様にして係止部材を製造した。前面に樹脂層が形成されているため係止部材が硬く、両端部を上に立ち上げて被覆材連結部を形成するのが困難であった。
Comparative Example 1
A locking member was manufactured in the same manner as in Example 1 except that a synthetic rubber-related resin was applied to the front surface of the first main surface. Since the resin layer is formed on the front surface, the locking member is hard, and it is difficult to form the covering material connecting portion by raising both ends.

比較例2
樹脂層Aを不連続に形成する代わりに連続に形成した以外は実施例1と同様にして係止部材を製造した。実施例1と同様にして係止部材を被覆材に取り付け、自動車用シートを作製した。係止部材を溝部の曲線形状に沿って変形させることが困難であり、被覆材固定作業の効率が極めて悪かった。
Comparative Example 2
A locking member was produced in the same manner as in Example 1 except that the resin layer A was formed continuously instead of discontinuously. The locking member was attached to the covering material in the same manner as in Example 1 to produce an automobile seat. It was difficult to deform the locking member along the curved shape of the groove, and the efficiency of the covering material fixing work was extremely poor.
